Last result of my today's lunch in park without lunch.
7,5mm long, not as fatty.

It certainly looks like it and not too many taxa in this family Micropezidae (synonym Tylidae in older books).Stilt-legged fly Calobata petronella almost certainly but we had better check . An expert in this group is Richard Merrit. He is in Alaska right now but I'll ask him to take a look at this thread. Robert

The Wikipedia site is a stub Sadwhich requires additions but it does link to further images (U.S.A though) and to an online key from the Manual of Nearctic Diptera.

No need: It is Calobata petronella. Though most of the genital structure is not well visible, it is not inconsistent with that species. In addition, the number of dorsocentral setae (two pairs) and the colour of the humeri (yellowish) point to C. petronella.

It is Calobata petronella. Without doubt.
